Onan Marquis 7000 Leaking Oil When Running
Leaks when runs does not seem to leak otherwise. Is not around dip stick or drain plug. Iv researched a little and seems it could be crankcase breather, seals etc.... Wasn't overfilled so I'm hoping ...

My 7500 started leaking oil and smoking while running. I found a welch plug that came out of a hole next to the governor housing and it was blowing oil out and letting it run down the center of the engine. I found the plug and reinstalled it with some sealer. Easy fix once I pulled the covers and found the problem.
